Are disposable e-cigarettes suitable for novices and girls?

Disposable e-cigarettes are not suitable for novices and girls. E-cigarettes are harmful to the body. Although high-quality e-cigarettes can reduce the public health pollution of cigarettes to a certain extent, there is currently no national standard and strict implementation of the standard. It is very harmful to novices and girls. Some of the answers above are not accurate. I will add here: RE: A RELX cartridge is equivalent to two packs of cigarettes, an average of one egg every 6-8 days A: A relx cartridge is 2ml of e-liquid, the nicotine ratio is 30mg/ml, the net nicotine content is 3%, and the net content of nicotine salt in 2ml is about 60mg, that is, the content of a single cartridge is 0.06g; a cigarette is generally 1.5-3mg, a pack of cigarettes has 20 cigarettes, and the highest nicotine content is 60mg; roughly speaking, the net nicotine content of a RELX cartridge is equivalent to a pack of cigarettes. Let's take a look at the number of puffs: the actual number of puffs of a 2ml egg pod is about 300 if I smoke normally, about 210 puffs of a 1.75ml small colored strip, and 800-1100k puffs of a very high-quality 5ml large-capacity pod, and the poor ones can be ignored; for cigarettes, I take about 6-8 puffs of a cigarette, so let's take 8 puffs, and I take 160 puffs of a pack of cigarettes, so one cartridge is indeed equivalent to the content of two packs of cigarettes; one cartridge is used every 6-8 days, and if I smoke, I smoke about 5ml of oil a day, one puff after another, after all, I don't need to relight, the more I smoke, the more I want to smoke; according to one cartridge every 8 days, it is about 40 puffs on average, 10 puffs in the morning, 20 puffs in the afternoon, and 10 puffs in the evening?
